Improvement in ventilators



UNITED STATES PATENT CDEEIOEo GEORGE R. MOORE, OF PHILADELPHIA,PENNSYLVANIA.

IMPROVEMENT IN VENTILATORS.

Speciiication forming part of Letters Patent No. 189,054, dated April 3,1877; application filed February 28, 1877.

To all whom it may concern Be it known that I, GEO. R. MOORE, of thecity and county of Philadelphia, and State of Pennsylvania, haveinvented new and useful Improvements in Ventilators, which improvementsare fully set forth in the following speciiication, reference being hadto the accompanying drawings.

The object of my invention is to furnish improved facilities forapplying a lighted lamp or gas-jet to the internal atmosphere of any ue,air-draft pipe, or chimney, whereby the circulation of air through thesame may be impelled whenever desired to increase draft for Ventilatingrooms,or any other places; also, to conserve the light of the said lampor gas-jet nearly as much as if the same were not in use forventilation.

Figure 1 is a front view of a section of airpipe containing myinvention, and showing a removable lamp standing in its proper place inthe niche of the said pipe. Beneath the front casing, as indicated bydotted lines, and a part in section, the air-passages a a a up past thelamp inclosure or niche are clearly shown. y

Fig. 2 is a vertical transverse section taken at right angles to Fig. l.In both these views the direction of the air-current is shown by arrows.4

Fig. 3 is a plan view taken just above the niche. It shows, also, indotted lines, a pivoted slide, c, for closing the passage b from theniche into the air-pipe when not in use by a lamp or gas-jet.

A is the part of the air-pipe, chimney, or flue, in which my inventionis more specifically included. B is a concaved niche placed externallyinto the flue, and forming the front wall of the same, so that the wholeis completed for ordinary use without the lamp, and when the lamp isused its body is not brought in contact with the internal air of theflue.

C is a lamp-chimney, placed centrally within the flue and supported at ashort distance above the niche, from which it extends up into theair-pipe D-in this instance in the ordinary form of air-pipe. It may beextended to any point desired. A

E is an ordinary lamp, removable at will. Its burner is fitted to passeasily through the aperture b into the flue proper, just beneath thestationary chimney G.

F is a hinged door or window, with mica center. It may be of glass, andof any desired color. It allows the light of the lamp. to pass into theroom, while all its heat is working to carry on ventilation by moving avolume of air through the ue. This window or door may, of course, bemade eitherwith or Without hinges, and of any size or shape desired.

The portion of the flue back of the light has a brightreflecting-surface, so as to conserve nearly all the light, and pass itthrough the window F.

Gr is a part of the flue in the ordinary form of air-pipe, and may beextended at will, and connected in any desired manner with any place tobe ventilated.

Let the section A be located wherever is most convenient or desirable,and then extend the other portions of the air-pipes so as fully to meetall requirements of the case.

H is an adjustable reflector before the window F. -It is hinged withsuflicient friction to hold its own weight, and may therefore be placedat any desired angle at will.

I claim- 1. The Hue-chimney or air-pipe A, provided with externallamp-holder or niche B, with its communicating aperture b into thesaidpipe or chimney, substantially as and for the ,purpose herein set forth.

2. In combination, the chimney or air-pipe A, niche B, internal chimneyC, and pipe D, substantially as and for the purpose herein set forth.

3, In combination, the air-pipe A, with aperture b and side door orwindow F, either with or without mica or glass, substantially as and forthe purpose herein set forth.

4. In combination, the air-pipe A, with ap! erture b and pivoted slidec, substantially as and for the purpose herein set forth.

5. In combination, the air-pipe A, with aperture b, mica or glass frontF, and a bright or reecting surface back of the light, substantially asand for the purpose herein set forth. l

6. In combination, the air-pipe A, lamp E, or gas jet, mica or glassfront F, and adjustable reflector H, substantially as and for thepurpose herein set forth.
